ABSTRACT:
A circuit and method for providing a plurality of voltage regulators whose outputs are constant for ranges of different external voltages are disclosed. The voltage regulators are made to be adaptable to two different ranges of external voltages through use of a master-slice technique. Furthermore, in a first voltage regulator, the supply current capability of the regulator is significantly increased under very low external voltage conditions. In a second voltage regulator, the voltage level on any node of the regulator does not exceed a voltage level that is too high, yet still sinks most of its current from the external power supply. A third voltage regulator is able to charge and discharge its output voltage so that it will maintain at a constant level. Finally, a fourth voltage regulator is optimized to reduce dielectric leakage.
